IMPROVEMENT IN ST OP-MOTIONS FOR WARPlNG-MACHINES.

Specification forming part of Letters Patent No. 125,689, dated April16, 1872.

SPEOIFIOATION.

I, FRANGIS HENRY PERRY, of Niagara Falls, in the county of Niagara,State of New York, have invented certain Improvements in Stop-Motion forWarpingMachines, of which the following is a specification:

Nature and Objects of the Invention.

- for the object of facilitating the work, securing greater perfection,and preventing unnecessary waste of material.

Description of Accompanying Drawing.

Figure lis a cross'sectional end view. Fig. 2 is a sectional side view.Fig. 3 is a sectional view of click-wheels L and L and winged roll M.Fig. 4 is a sectional view of friction driving-pulley K K and forkedspring-lever W, and W the brake. Fig. 5, a pendant.

General Description.

S is the spooler section. G is the creel-section. B is the mainwinding-drum. A is the receiving-spool. U is the main lever andbalancing weights and bridge-wires c and d. D is the side lever withadjustable weights. F is the creel-board and pins. E is the threadhookM, winged roll. H is a roll. Land L are the click-wheels. N is therocker. O is the connecting-rod. R and R are the horizontal levers. Kand K are the friction-pulleys to drive the machine. I is thethread-guide. P is the vibrating lever. J is the cam-motion. W is thebrake. T is the pendant. W is the forked spring-lever.

Operation.

The yarn is placed upon the creel pins upon creel board F 5 the end ispassed up over hook E, down through the guide-wires, and between thewires 0 and dupon 0 and I), up over roll H, down through the notches onguide I, to the receiving-spool A.

A band connects click-wheels L and L from K, from whence it receives itsmotion. Lever R being pushed to the right causes lever R to move to theleft, which operates the spring forked lever W and closesfriction-pulley K upon its complement K, which is fast to drum shaft B,thus starting the machine. At the same time connectingrod O is drawndown into notch on lever R by an encircling spiral spring; alsooperating on rocker N, closing click-wheel L into its mate L upon shaftof winged roll- M. The whole machine being now in operation willcontinue until some of the threads break or run out.

It will be observed that the motion of the machine will draw the leversG and D up toward the roll H and depress the opposite end out of the wayof the revolving winged. roll M.

Now, in case any thread breaks or runs out the front end of the leverwill fall, causing the notch on its opposite end to lock with the wingof roll M, which stops it. Click-wheel L, owing to its conicalprojections, will be pushed laterally against rocker N, causingconnecting-rod O to rise out of notch on R, when the forked spring-leverW will instant- 1y throw the'friction-pulley K off, and at the same timeapply the brake W to K, thus causing the machine to stop.

When using very fine slack-twisted yarns, silk, or cotton, thefriction-levers are dispensed with and pendant T dropped down throughthe front end of main lever U to winged roll M, placed below, as shownin Fig. 5.

When the machine is put in motion the thread draws up the pendant T, thelower extremity of which, when down, locks the wing of roll M in amanner similar to the notch on the opposite end of lever G producinglike results.
